松辽盆地南部坳陷期层序地层研究
|
摘要
在综合分析钻井、测井、地震等各种资料的基础上,对松辽盆地南部坳陷期的层序地层进行了划分。结果表明,此地区坳陷期的层序地层可划分为2个超层序,9个三级层序,其中三级层序的内部结构具有三分(低水位体系域、湖侵体系域和高水位体系域)和二分(湖侵体系域、湖退体系域)两种。在层序的划分过程中建立了浅水区域层序界面的识别标志,即暴露剥蚀面、河道冲刷面、地层叠加型式转换面及泥岩颜色突变面。将ΔlgR法和锰、铁元素法用于深水区域层序界面的识别,层序界面对应ΔlgR和w(Mn)/w(Fe)的低值,最大湖泛面对应ΔlgR和w(Mn)/w(Fe)的峰值。详细研究了二分层序和三分层序的层序特征,并阐述了其与油气的分布关系,即二分层序以下生上储型油藏组合为主,三分层序以上生下储型油藏组合为主。
Based on drilling,logging and seismic data,formation of depression period in southern Songliao Basin can be divided into two supersequences and nine third-order sequences.And third-order sequence is further divided into three systems tract including lowstand,lacustrine transgressive and highstand systems tract,and two systems tract including lacustrine transgressive and lacustrine regressive systems tract.Identification marks of shallow-water sequence boundary were established, that is exposure erosion surface,channel scouring surfaces,formation stacking transformation,surfaces showing abrupt changes of mudstone color.ΔlgR and w(Mn)/w(Fe) are used to identify sequence boundary of deep-water.ΔlgR and w(Mn)/w(Fe) are the low value in the sequence boundary,which are the peak value in maximum flooding surface.The sequence characteristics of dichotomy sequence and tripartition sequence and the relationship of sequence stratigraphical units with oil and gas were discussed.Reservoir combination of generation lower zones and preservation in upper zones is mainly in dichotomy sequence,and reservoir combination of generation upper zones and preservation in lower zones is dominant in tripartition sequence.
